SPECIFICATION forming part of Letters Patent No. 312,183, dated February10,1885.

Application filed March (3, ISM. Renewed December-13, 1834. (X0 model.)

serve the purpose of locking the brccch-closing bolt, and, secondly, tothe carrier, by

means of which the cartridges :1 re raised into line with the bore ofthe barrel.

The leading features of the invention and the subordinate details arefully described hereinafter, and are specifically indicated in theclaims.

In the drawings, Figure 1 represents a vertical longitudinal section ofthe receiver and breech-closing bolt, with part of the magazine andbarrel, the contained and contiguous parts being in side elevation. Fig.2 shows the same view with the parts in different positions. Fig. 3 is aplan view of the carrier.

The first feature of the invention is the slid ing block on which theoperating triggcrguard lever is pivoted, which serves to move the boltand to lock it in place. This lever is shown at I) Z) the former notinthe u 1 )er s ll part, or that within the recciv r, and the latter thatoutside or below the receiver. The upper end of this lever is pivoted tothe bolt A by a pin, 0, so as to turn on the pin when the lever israised from the position of Fig. 1 to that of Fig. 2. It is pivotedclosely to the bolt, so that there is no movement upon the pin exceptthat of turning. The firing pin 1 passes through the bolt above thepivot c, the forward end being reduced to leave a shoulder, 2, whichbears against the bottom of a recess within the lever. The lever ispivoted upon a sliding block or swivel, d, this block being equal inwidth to that of the lever. The block is bored, as shown at e, toreceive a spring, and at its forward end is slotted transversely toreceive a pin, f, set in the walls of the receiver. pin f, and tends topush the block to the rear. The lever is formed with the shoulderibehind its pivot, said shoulder being preferably made upon a curvestruck from the-pivot 0. Then the lever is in position shown in Fig. 1,this shoulder bears against a corresponding seat in the rear part of thereceiver, and being pressed rearward by the spring, locks the boltsecurely in its place. The firingpin, when the lever is in positionshown in Fig. 1, rests in its advanced position with the shoulder 2against the bottom of the socket or cavity. The first effect of theforward movement of the lower part of the lever is to start back thefiring-pin, and the lever holds this slightly retracted until the boltis returned to its seat in the breech. The pivoting-block d ispressedforward when the upper part begins to move backward, and the shoulder tof the lever drops from its seat, thus unlocking the bolt. Furthermovement of the lever throws back the bolt to the position shown in Fig.2., at the same time cooking the piece. By this construction great forceis applied to the bolt with a minimum of friction.

The carrier is of special and improved form. It is shown in sideelevation in Figs. 1 and 2, and in plan view in Fig. 3. It is pivoted ath in the chamber of the receiver, and its forward end is adapted toswing up from the position shown in Fig. 1 to that shown in Fi 2. It ismade in two parts, as shown in Fig. 3, the part in constituting one sideand the part a the other side. These parts are connected by a bolt, Z,which is fixed to one part and is loose in the other. Each part isprovided with an upwardly-projecting ear, 7;, the upper parts of whichears incline slightly inward to hold the cartridge. The rear ends of thesides are inclined also slightly inward, as shown at 0 0. The two sidesare pivoted separately, each turning upon a small stud set into thewalls, and the pivoting is sufficiently loose to allow the forward endsof the carrier to be slightly spread or narrowed. The lever moves in thespace M in the rear part of the carrier, between the sides, and as itreaches the inclines o o 011 the rear ends of the two parts of Thespring bears against the 0 the carrier it presses them apart, and thuscauses the front ends to approach each other to grip the cartridge. Assoon as the leverA is returned to carry forward the cartridge and closethe breech it leaves the inclines 0 o, and thus permits the front endsof the carrier to spread and release the cartridge. The forward end isadapted, when spread, to receive the cartridge, and when closed toretain the cartridge by means of the inward inclination of the ears 7c.The rear ends of the carrier extend upward,and are provided withshoulders 4, which are struck by projections 5 on the front ends of thebolt when the bolt is in the latter part of the movement to the rear,and after it has pressed between the inclines 0 o. to cause the carriersto grip the cartridge. This throws up the front of the carrier end inthe ordinary manner. An ordinary retractor, 3, serves to draw back theempty shell. The ejector consists of the studti, which fits in a holebored in one side of the bolt, in which it is held by a pin. It has freebut limited movement, and just before the bolt reaches its rearmostlimit the end of this stud strikes against the shoulder 4 and is thrownforward into position shown in Fig. 2. As the forward end of the shellhas at that time cleared the barrel, it is thrown out by the projectingend of the stud. At the same the project-ion 5 has caused the forwardend of the carrier to rise with the cartridge received from themagazine. It is held up by pressure of the magazinespring against itsforward end. Luring the rise of the carrier the cartridge is grippedsecurely by the inward movement of the walls,

caused by the rearward movement of the part b of the lever pressingbetween the inclines 0 0, as heretofore explained. This gripping takesplace just before the rise of the carrier. The reverse movement of thecarrier, which brings forward the bolt and drives the eartridge to itsseat, at the same time throws down the carrier, ready for anothercartridge. The last part of the movement of the lever locks the bolt inplace and lets the end of the firingpin rest upon the cartridge.

WVe claim as our invention 1. In a breech-loading fire-arm, and incombination, a bolt for closing the breech, and a lever connected to thebolt and pivoted on a sliding block provided with a spring, said leverhaving a seat in the receiver, whereby it locks the bolt, allsubstantially as described.

2. In a breech-loading fire-arm, and in combination with ahorizontally-moving breechclosing bolt and operating-lever pivotedthereto. a carrier composed of two parts pivoted separately.for verticaland slight lateral movement, the front ends of which parts are providedwith ears adapted to grip the cartridge, and the rear ends formed withinclines adapted to the lever which is located between the two parts,all substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
